Well, I thought that in HTML closing tags were just optional for empty
elements, I didn't thought they must not appear.
Thanks for the information !

I think I wasn't clear enough in my last message : in my input
file, <INPUT> tags are not closed and I cannot close them by
myself, because its HTML code is produced by an HTML editor (the
one included in WSAD).
In the HTML 4.01 DTD we find
<!ELEMENT INPUT - O EMPTY -- form control -->
This means that the *ONLY* legal form of an <INPUT> element is
<INPUT att=val....>
Not only do you not *need* a </INPUT> tag,
you aren't *allowed* to have one. Quoting the SGML standard,
"empty elements do not have end-tags" (meaning elements *declared*
to be EMPTY, not elements that just happen to be empty).
More explicitly, 7.3 says
If an element has a declared content of "EMPTY" [which INPUT does],
or an explicit content reference [not used in HTML], the end-tag
****MUST**** be omitted [my emphasis].
In XML, empty elements may be written as
<tag att=val...></tag>
with absolutely nothing between > and </ or as
<tag att=val.../>
so in *X*HTML you have to write
<input att=val.../>
with lower-case "input".
To repeat, in HTML input or output, there MUST NOT be any </INPUT>
end tags, while in XHTML input or output there may be </input> end
tags or <input .../> empty tags may be used.
